We deduce a fractional integral equality for twice differentiable mappings defined on an m-invex set. By using this equality, we obtain new estimates ......

We establish some new extensions of Hermite-Hadamard inequality for fractional integrals and present several applications for the Beta-function.

We introduce a (p, q)-analog of the poly-Euler polynomials and numbers by using the (p, q)-polylogarithm function. These new sequences are generalizat......

Within the framework of variable-exponent Morrey and Morrey-Herz spaces, we prove some boundedness results for the commutator of Marcinkiewicz integra......
